概括
COVID-19 改变了阿波利波蛋白水平和高密度胆固醇组成,在未幸存者中水平较低. 像ApoH这样的特定标志物比标准脂质水平更好地预测死亡率.
科学领域:
- 生物化学 生物化学
- 免疫学 免疫学 免疫学
- 病理生理学 病理生理学
背景情况:
- SARS-CoV-2 感染影响脂质代谢和肺功能,疾病严重程度与降低高密度脂蛋白 (HDL) 和低密度脂蛋白胆固醇有关.
- 很少有研究研究了COVID-19期间脂蛋白的结构变化.
- 在SARS-CoV-2感染动态中,阿波利波蛋白水平和HDL颗粒组成至关重要.
研究的目的:
- 评估在重症监护室 (ICU) 住院的COVID-19患者的阿波利波蛋白水平.
- 为了比较ICU幸存者和非幸存者之间的HDL粒子大小和蛋白质组.
- 为了确定COVID-19死亡率预测的潜在生物标志物.
主要方法:
- 质谱法用于量化37名COVID-19患者的14种阿波利波蛋白和LCAT的血水平.
- 原生聚烯胺凝电泳分析了HDL亚种群分布.
- 从幸存者和非幸存者中分离出HDL颗粒,并使用NanoLC-MS/MS来表征它们的蛋白质组.
主要成果:
- 不幸存者表现出阿波利波蛋白Apo A-II,Apo Cs,Apo H,Apo J,Apo M和LCAT的血水平降低.
- 关于死亡率,没有观察到HDL亚群分布的显著变化.
- 在幸存者和非幸存者之间,HDL组成有所不同,在非幸存者中,Apo H和偏氧酶3的显着下降.
结论:
- 血 Apolipoproteins 和 HDL 组成的显著变化区分了幸存者和不幸存的 COVID-19 患者.
- 脂蛋白H (Apo H) 是比基线HDL胆固醇 (HDL-C) 水平更强大的COVID-19死亡预测剂.
- 这些特定的阿波利波蛋白标记物为COVID-19患者的死亡风险提供了更准确的指标.

Simple proteins and protein complexes contain only amino acids. In contrast, many other proteins, called conjugated proteins, covalently bond with non-protein moieties.
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...

A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...
